Drilling between custom charts
I'm trying to make a tool using custom charts for our building, but I'm not sure about the feasibility of my design idea. Essentially, I'm trying to recreate the drill down process to Zip Code shown in this DOMO video: https://www.youtube.com/watch?v=UUZ_RvKX8O8&ab_channel=Domo, but instead using custom maps of our facility, with each "state" being a different department (accounting, engineering, etc.) Inside each department, I would want another custom chart showing the layout of that specific department, just like how each state is divided into zip codes.
I've already created a custom SVG map of the facility, but I guess I'm having a hard time wrapping my head around how I could "zoom" into each different department the way it's done in the video I linked. Any help would be appreciated.
